| 20080202269 | STRAIN WAVE REDUCTION GEAR AND VARIABLE TRANSMISSION RATIO STEERING APPARATUS - A strain wave reduction gear and a variable transmission ratio steering apparatus move a flexible gear and a rigid gear differentially, even if the flexible gear is in a fractured state. According to the strain wave reduction gear, the flexspline mates with the inner side of the elliptical hole of the rigid cam via the flexible bearing; therefore, the flexspline maintains an elliptical shape that is similar to the elliptical hole and maintains the meshed state—even if the flexspline fractures. Therefore, when the rigid cam rotates, the mesh positions of the flexspline and the first and second circular splines can be shifted in a circumferential direction. Namely, even in a state wherein the flexspline is fractured, the first circular spline and the second circular spline can be moved differentially by the difference in their tooth counts. | 08-28-2008 |

The second teeth cooperate with the first teeth so that rotation of the pinion causes translation of the rack. The rack is deformable elastically, such that when a force is exerted on it in the direction opposite the direction of translation during rotation of the pinion, it undergoes elastic deformation. The housing leaves clearance for the rack, in the plane of rotation of the pinion and perpendicular to the direction of translation, at least equal to the least of the heights of the first and second teeth, such that when the rack undergoes elastic deformation, that of the second teeth in cooperation with the first teeth disengages from the latter. | 08-27-2009 |
| 20090260467 | STEERING RACK AND METHOD OF MANUFACTURING THE SAME - When a punch is downwardly pressed, an inner circumferential surface of a first rack blank bites into a top surface of a second rack blank. A blank material upwardly flows due to a reaction force and is used to form rack teeth. Thus, a filling degree of the teeth with the material is enhanced. At the time when the forming of the rack teeth is finished, a gap is left between the inner circumferential surface of the first rack blank and the outer circumferential surface of the second rack blank. Thus, a die is not put into a sealed condition. Consequently, a forming load is small so that the lifetime of the die is lengthened. Also, the top surface of the second rack blank bites into a bore hole portion of the first rack blank so that the first rack blank and the second rack blank are joined together. Accordingly, the rigidity of the entire rack teeth is increased. | 10-22-2009 |

| 20160131242 | RACK BUSH AND STEERING SYSTEM - A rack bush for supporting a rack shaft in a rack-and-pinion steering system so that the rack shaft slides in an axial direction thereof includes a teeth side support portion and a back side support portion. Rack teeth are formed in a first area of an outer circumferential surface of the rack shaft. The teeth side support portion contacts a second area of the outer circumferential surface to support the rack shaft from a teeth side where the rack teeth are formed. The second area lies adjacent to the first area in the axial direction. The back side support portion contacts a third area of the outer circumferential surface to support the rack shaft from a back side other than the teeth side. The third area is positioned out of the first area in a circumferential direction around an axis of the rack shaft. | 05-12-2016 |
| 20160144789 | Movement Mechanism and Wing Mirror for a Vehicle Provided with Such a Movement Mechanism - A movement mechanism comprising a substantially spherical holder and a substantially bowl-shaped ring, which are rotatable relative to each other about a first axis and a second axis enclosing an angle of approximately 90° to the first axis. Driving means are provided for enabling movement of the holder relative to the ring and comprise a first non-straight driving rod bearing-mounted in the holder, as well as means for activating the driving rod and a second non-straight driving rod bearing-mounted in the holder, as well as means for activating the driving rod. The first driving rod and the second driving rod are rotatable about a third and a fourth axis, respectively, which third and fourth axes are mutually parallel and lie in a plane equal or parallel to the top face of the holder and which third and fourth axes are parallel to or coincide with the first axis. | 05-26-2016 |
| 20160160913 | RADIALLY DEFLECTABLE BUSHING AND STEERING GEAR ASSEMBLY USING THE SAME - A bushing is provided for adjusting to differences in diameter between concentric elements of an assembly. The bushing may be provided with a plurality of leaf springs coupled to one another to form parts of a wall. The bushing wall may have a first contact face and a second contact face opposite the first contact face. The bushing wall may also be configured to be positioned in a generally annular shape. Each of the leaf springs forming part of the bushing wall may be radially deflectable relative to each of the other leaf springs in order to self-align the bushing by the resilient response of each leaf spring. | 06-09-2016 |
